And yes, the PRISM scandal is far, far from over. More and more information keeps leaking out, and the more gets out, the worse it gets. The companies involved have sent out official statements - often by mouth of their CEOs - and what's interesting is that not only are these official statements eerily similar to each other, using the same terms clearly designed by lawyers, they also directly contradict new reports from The New York Times. So, who is lying?

Companies are lying (at least by omission), they must not be trusted.
They could be trusted more if they said : "everything you write or wrote may be accessible by the NSA"

Their attitude is also very arrogant.
When Google says "we don't share our server's contents", it means that want to keep it for themselves, not that they are making efforts to make difficult the systematic exploitation of data.
